thanx everyone. they asked if i wanted sedation and i wasnt sure, they said i could try without and change my mind. the doctor never even spoke to me when i got in the room, he had a face like thunder. strated the procedure and i shouted for them to stop as i knew at that point it was going to be too much but he didnt stop and they kept telling me to top shouting. i was wretching and wretching and thought i was dying! when it was done, i was asking questions and he wasnt giving me any proper answers, in fact he was getting his suit jacket on and left before i did, seemingly in a rush!
